SIPI-ION CONTROL DEVICE.

Specification of Letters Patent.

Patented May 116, 1922.

Application filed August 20, 1920. Serial No. 404,930.

T 0 aZZ whom it may concern:

Be it known that 1, AUGUST W. BRATER, citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Siphon Control Deyices, of which the following is a specificaion.

devices, and one of the principal objects is to produce a device of this nature which shall be simple of construction, cheap to manufacture, and eflicient for the purpose for which it is designed.

Another object is to provide a siphon which will not clog from sediment in the liquid flowing therethrough.

Another object is to provide a device for holding a siphon tube so that a kink may be readily produced in the tube for cutting I off the flow.

Another object is to provide a device of this nature with'means whereby the tube may be held in a kinked condition.

Another object is to provide automatic means for effecting a kinking of the tube by bending or folding a portion of the tube upon itself.

With these and other objects in view, the invention consists in certain novel construction and combinations and arrangements of parts, the essential elements of which are hereinafter fully described and claimed, and are shown in the accompanying drawing comprising two sheets, in which:

Figure 1 is a side elevation of my improved siphon control device arranged for automatically'shutting oil the flow of liquid, the parts being shown in the position assumed when the flow is unobstructed.

Figure 2 is a similar view but showing the parts moved to position to obstruct the flow of the liquid.

Figure 3 shows a spring controlled device for a portable cut-off adapted for use on fountain syringes. Figure 4 shows a form of lever control for the cut-off.

This invention relates to siphon control Figure 8 is the device as embodied in a portable control for fountain syringes and the like. I

Figure 9 shows a device similar to Figures 1, 2 and 7 but for producing a single kink.

Figure 10 represents a modified form of single kink device.

Like characters'of reference in all views refer to like parts.

Referrin particularly to the form of the invention s own in Figures 1 and 2, 1 represents a standard or support which may be of the kind shown in the drawings or of any other suitable'form. Adjustably supported upon this standard is a frame structure 2 having a depending arm 3 which is bent into or otherwise formed with a horizontally extending portion 4 which has its central portion cut away at 5 to permit the passage of the neck of a float member 6. Secured in the side of member 3 is a pair of screws, nails or similar headed members 7 which are adapted to cooperate with respective bayonet slots 8 in a member 9. Member 9 is a piece of springy metal which is folded at its ends and formed at 10 and 11 to support a rubber hose or tube 12 which forms a segment of a circle at 13. A member 14 is provided with a pair of upwardly bent flanges l5 and with a pair of down wardly bent flanges 16. The neck of the float member 6 is extended up through an aperture in member 14; and is provided with a head 17 which secures member 6 to member 14. Flanges 16 are pivoted at l7 so as to permit an upward swing of member 1 1 and member 14 is provided with a bent up portion 17* adapted to limit such swing.

Pivoted to member 4 is a frame member 18 which comprises a pair of side arms 19 connected by a cross-bar 2O A pair of wires 21 connect pivotally with arms 19 and the flanges 15.

It will readily be seen that if the float is placed in a vessel and the tube 12 conducts liquid into that vessel, that when the level of the liquid rises to the desired height it will raise the float 6 and thereby the table 14 so that the wires 21 will move the arms 19 about their pivots until the cross bar 20 presses on the arcuate portion 13 of the tube so as to effect a kinking thereof substantially as shown in Figure 2. It will readily be understood that if desired the member 9 can be detached from the member 3 and in this condition forms a portable cut-ofi' for the tube in the operation of which cut-off the tube is pushed in by hand at 13 and hooked over an outstanding finger 410 formed on the edge of the member 9.

y In Figure 3 is shown a portable cut-off in which a frame member 22 is provided with tube holding portions 23 and 2 1 and at its center is provided with a slot 25 through. which protrude the ends of a compressible spring 26 which will normally hold the tube in the open condition as shown in full lines but upon pushing in the portion 13 of the tube to the dottedline position, the spring will expand as shown in dotted lines and hold the tube in its kinked position for effecting a cut-off. I

In the form of the device shown in Figure 4 a similar frame member to that used in Figure 3 is provided, and tothe portion 24 there is pivoted and arm 27 which passes around the tube at 28 and which is provided with a finger piece 29. Near its pivot, arm 27 is provided with a finger 30 which is adapted to operate against a spring finger 31 bent upfrom member 24 so as to hold the arm 27 in either the full line position or the dotted line position. By pressing finger 29 toward the frame member 22 the tube portion 13 may be kinked to effect the cutoff and will be held in this condition by the co-action of the fingers 30 and 31untilmember 29 is moved in the opposite direction.

In'Figure 5 is shown a device similar to that in Figure 1 but in which a weight 32 mounted in the bracket 33 is adapted to con trol portion 13 of the tube. This style is best adapted for stationary use.

In Figure 6 a spring 34 is provided which is connected to a collar mounted on the portion 13 and which collar is provided with a loop 36 which is adapted to be fastened over a trigger diagrammatically shown at 87 and which may be tripped by an ordinary scale or weighing device in any suitable manner so as to release the spring 3 1- to draw member 35 in to thereby kink the portion 13 of the tube. In Figure 7 a float and table are used as 1n Figure 1, but the tube is attached to the table and as the float raises the table, the tube is moved to the dotted line position thereby forming a single fold or kink to close off the flow of the liquid.

In the modified form shown in Figure 8, the device is similar to the member 9 shown m Figure 1 but is devoid of the apertures or bayonet slots 8 for supporting the inember and the structure is made of rigid stock instead of springy material. This device is adapted for use on all sorts of portable devices such as fountain syringes.

InFigure 9 is shown a modified form of the single kink device of Figure 7. As the float is raised, the table to which the tube 1s secured,moves: the tube to the dotted 'li'ne position thereby kinking the same to shut off the flow.

In the form shown in Figure 10, the raisinc; of the float causes the movement of the parts from their full line position to the dotted line position thereby causing the bending or folding of the tube on itself as shown in dotted lines, whereby the flow of liquid is stopped.

Particular emphasis is laid on the fact that while there are shown a number of ways of producing the result, the principle is the same in all,viz., the producing of a single or double kink by bending a portion of a tube or folding the same upon itself. This I consider to be my invention.

While I have described what I deem to be themost desirable embodiments of my invention, it is obvious that many of the details may be varied without in anyway departing fromthe spirit ofmy invention; and I therefore do not lilnit myself to-the exact details of construction herein set forth, nor to anything less than the whole of my invention limited only by thev appended claims.

lVhat I claim is 2- 1. The combination of a frame carrying inlet and outlet tubes attached;continuously to a semi-circle of flexible tubing. and provided with a finger to retain a double kink produced by moving said semi-circle of-flexible tubing at its curved portion toward the center of curvature by folding or bending a portion ofthe tube on; itself and thereby controlling the flow of liquid through thede vice.

2. In a device of the class described, the combination of a flexible tube, a piece of springy material bent so as to form means for supporting said tube in are formation and provided with a finger for maintaining said tube in kinked' condition.

3.
